状语从句知识点详解（初中英语专项复习）状语从句的概念: 用一个句子作状语来修饰动词和形容词，以表明动作发生或状态存在的时间、地点、原因等，这个句子就叫做状语从句。
状语从句的分类：状语从句共分为九大类，包括：时间、地点、原因、条件、让步、目的、结果、方式、比较状语从句。
下面分别讲解：一、时间状语从句概念：用来表示时间的状语从句，由when, while, as, till, until，before, after, since等引导。
由于时间状语从句的引导词所表示的意思并非一致，不同引导词表达不同的时间，它们在句子中对应的时态、语态等也有所不同。
例如：when /while引导的时间状语从句when引导的从句的谓语动词通常是瞬间动词，也可以是延续性动词。
从句动作可与主语动作通常先后发生也可同时发生。
I was writing when my sister came back.( come是瞬间动词，只能用when引导，不能用while)He often wrote me when/while he studied in Shanghai International Studies University.( study 是延续性动词，while可代替when)While my mother was cooking , I was playing chess with dad. (cook是延续性的动词，cook和play同时发生)I like playing chess while my sister likes reading stories.我喜欢下棋，而我姐姐喜欢看小说。
(while表示对比)when和while的区别还有：while引导的时间状语从句多用于进行时态，而when引导的时间状语从句多用于一般时态。
While we were playing games, our headmaster called me .我们正在做游戏的时候，校长叫我了。

八种状语从句
八种状语从句状语从句在句中作状语，修饰主句中的动词、形容词和副词等。
按其作用和意义可分为时间、原因、目的、结果、条件、让步、方式、比较八种。
下面对这八种从句的要点加以总结。
一、各类状语从句的引导词及易混词的区别。
1. 时间状语从句1) 引导词（1）表示“当……时候”：when, while, as, whenever（2）表示“一……就……”：as soon as（3）其它：after, before, since, until, by the timeWhenever he comes, he brings a friend. 他每次来都带个朋友。
I want to see him as soon as he arrives. 他一来我就要见他。
I went to bed after I finished my homework. 我做完家庭作业之后才睡觉。
2) 易混引导词when, while, as 的区别when既可指“时间点”，与瞬时动词连用，也可指“时间段”，与延续性动词连用（这时可与while互换）。
如：When he came in, his mother was cooking. 他进来时，他妈妈正在烧饭。
When（While）we were at school, we went to the library every day. 我们在校求学时，每天都到图书馆去。
while 只表示时间段，因此while从句的谓语动词要用延续性动词。

as 与when 用法相似，但着重强调主句动作与从句动作同时发生，有“随着……”或“一边……一边……”之意。
